Description of key information

he bigger part of the test item eluted with a retention time of > 90 min corresponding to a log Koc of > 5.0 at 25 °C based on the results of HPLC determination.

Key value for chemical safety assessment

Koc at 20 °C:
100 000

Additional information

A part of the test item eluted in a retention time range from 1.601 min to 5.537 min corresponding to a log Koc range from < 1.5 to 1.76 at 25 °C based on the results of HPLC determination. The log Koc value of the lower range is below the lower determination limit of the method (determination limit log Koc = 1.5). The bigger part of the test item eluted with a retention time of > 90 min corresponding to a log Koc of > 5.0 at 25 °C based on the results of HPLC determination. The log Koc value is above the upper determination limit of the method (determination limit log Koc = 5.0).

[LogKoc: 5.0]
